| 4 | 人工智能干预性临床试验报告指南:CONSORT-AI扩展显示文摘《试验报告统一标准》(Consolidated Standards of Reporting Trials,CONSORT)2010声明提供了报告随机试验的最低准则。它的广泛使用有助于保证评估新的干预措施的透明性。最近,人们越来越认识到,涉及人工智能(artificial intelligence,AI)的干预需要经过严格的前瞻性评估,以明确其对健康的影响。《人工智能试验报告统一标准》(Consolidated Standards of Reporting Trials Artificial Intelligence,CONSORT-AI)是一个新的临床试验报告指南,用以评估具有AI成分的干预。它是与《人工智能干预试验方案报告标准》(Standard ProtocolItems:Recommendations forI nterventional Trials-Artificial Intelligence,SPIRIT-AI)同步编制的。这两项指南的编制通过分阶段的文献回顾和专家咨询等过程达成共识,产生29项候选条目。由国际多方利益相关者小组在两阶段德尔菲调查(103个利益相关者)中对这些条目进行了咨询,并在共识会议上达成一致意见(31个利益相关者),通过34个试点参与进行改进和优化。CONSORT-AI扩展包括14项新条目,这些新条目对于AI干预非常重要,除了2010年CONSORT声明的核心条目之外,试验报告还应常规包含这些内容。CONSORT-AI建议研究人员提供关于AI干预的清晰描述,包括使用AI所需的说明和技能、AI干预集成环境的设置、输入和输出数据处理的注意事项、人-AI交互和错误案例分析。CONSORT-AI将有助于提高AI干预临床试验方案的透明度和完整性,也有助于编辑、同行评审以及普通读者理解、解释和严格评估临床试验的设计和偏倚风险。 | 李子孝(译) 熊云云(译) 丁玲玲(译) 王春雪(译) 赵性泉(译) 王拥军(译) WANG Chun-Juan LIU X X CRUZ RIVERA S MOHER D | 2020 | 中国卒中杂志2020,15,12: | 19 |

| 8 | MicroRNA-185通过靶向调节DN-MT1/PTEN/Akt通路抑制肝细胞癌的生长显示文摘近来研究表明miRNAs与肝癌的发生密切相关,然而单个miRNAs的具体作用机制仍未完全阐明。作者对microR-NA-185(miR-185)在肝细胞癌生物学功能和分子机制方面做了一些研究。实验发现,与非肿瘤性的肝脏实质相比, miR-185在人肝细胞癌组织中的表达减少;qRT-PCR检测显示,与原代肝细胞相比, miR-185在人肝细胞癌细胞中的表达下降;在体外人肝细胞癌细胞中miR-185的过表达会抑制细胞的增殖和侵袭,并且阻止SCID小鼠体内肿瘤的生长。miR-185的过表达能够抑制肝细胞癌细胞中DNMT13′端非翻译区域荧光素酶的活性,当 miR-185结合位点发生突变时,就不存在该效应;miR-185的复制或过表达会减少肝细胞癌细胞中DNMT1蛋白的表达。这些结果表明DNMT1是miR-185在肝细胞癌细胞中的靶向作用蛋白。 DNMT1在miR-185诱导抑制肝细胞癌的增殖中所起的作用,可进一步通过DNMT1的过表达阻止miR-185诱导抑制肝细胞癌细胞的增殖和侵袭这一事实所证实。 miR-185的复制或过表达能够减少PTEN启动子DNA甲基化并且提高PTEN的表达,从而抑制Akt磷酸化;如果DNMT1过表达,这些效应刚好相反。以上结果表明:miR-185靶向作用于DNMT1,通过诱导PTEN和抑制Akt,从而抑制肝细胞癌细胞的增殖,活化或激活miR-185可能成为肝细胞癌新的治疗策略之一。 | Qadir X V Han C Lu D 魏建国 许春伟 | 2014 | 临床与实验病理学杂志2014,30,12: | 12 |
| 9 | Mechanosignaling activation of TGFβmaintains intervertebral disc homeostasis显示文摘Intervertebral disc(IVD) degeneration is the leading cause of disability with no disease-modifying treatment.IVD degeneration is associated with instable mechanical loading in the spine, but little is known about how mechanical stress regulates nucleus notochordal(NC) cells to maintain IVD homeostasis. Here we report that mechanical stress can result in excessive integrin α_vβ_6-mediated activation of transforming growth factor beta(TGFβ), decreased NC cell vacuoles, and increased matrix proteoglycan production, and results in degenerative disc disease(DDD). Knockout of TGFβ type II receptor(TβRII) or integrin α_v in the NC cells inhibited functional activity of postnatal NC cells and also resulted in DDD under mechanical loading.Administration of RGD peptide, TGFβ, and α_vβ_6-neutralizing antibodies attenuated IVD degeneration. Thus,integrin-mediated activation of TGFβ plays a critical role in mechanical signaling transduction to regulate IVD cell function and homeostasis. Manipulation of this signaling pathway may be a potential therapeutic target to modify DDD. | Qin Bian Lei Ma Amit Jain Janet L Crane Khaled Kebaish Mei Wan Zhengdong Zhang X Edward Guo Paul D Sponseller Cheryle A Seguin Lee H Riley Yongjun Wang Xu Cao | 2017 | Bone Research2017,5,1: | 9 |

| 14 | Prevalence and dietetic management of mild gastrointestinal disorders in milk-fed infants显示文摘AIM: To assess the prevalence of mild gastrointestinal disorders in milk-fed infants in paediatric practice, and to evaluate the effectiveness and satisfaction with dietetic treatment.METHODS: A cross-sectional epidemiological study was first carried out. A total of 285 paediatricians included 3487 children seen during a period of one week. In a second phase an observational, prospective and multicentre study was conducted and 2069 milk-fed infants with mild gastrointestinal disorders (colic, constipation, regurgitation and diarrhoea) were included. There was a baseline visit (start of treatment) and a final visit four weeks later. The effectiveness of the various Novalac formulas, as well as the satisfaction of the parents/tutors and paediatricians with the dietetic treatment were assessed at the final visit.RESULTS: The prevalence of mild gastrointestinal disorders was 27.8% of all paediatrician consultations (9.2%, 7.8%, 6.1% and 4.6% in relation to colic, constipation, regurgitation and diarrhoea, respectively). The several Novalac adapted milk formulas resolved 88.4% of the mild gastrointestinal disorders. Depending on the type of disorder, differences in response rate were observed. The highest effectiveness was recorded with respect to diarrhoea (92.6%), followed by constipation (91.6%), colic (87.6%) and regurgitation (81%). Overall, 91% of the paediatricians and 88.8% of the parents/tutors were satisfied or very satisfied with the Novalac adapted milk formulas.CONCLUSION: Mild gastrointestinal disorders show a high prevalence in paediatric practice. The Novalac adapted milk formulas have been shown to be effective in treating mild gastrointestinal disorders in milk-fed infants in the context of routine clinical practice. | D Infante Pina X Badia Llach B Ario-Armengol V Villegas Iglesias | 2008 | World Journal of Gastroenterology2008,14,2: | 5 |
| 15 | Value of a new stick-type rapid urine test for the diagnosis of Helicobacter pylori infection in the Vietnamese population显示文摘AIM:To assess the value of a new test for the diagnosis of Helicobacter pylori(H.pylori) infection,Rapirun H.pylori Antibody Stick(Rapirun Stick),in a Vietnamese population.METHODS:Eligible patients without previous history of H.pylori eradication were recruited.Rapid urease test(RUT) and histologic examination were used to diagnose the H.pylori infection.Patients were considered H.pylori positive when the RUT results were positive and/or the bacteria were detected histologically.Rapirun Stick tests were performed using urine samples,and the results were compared with the other 2 methods.RESULTS:We enrolled 200 patients with a mean age of 36(range,18-76) years.There were 116 females and 84 males.Of the 200 patients,111(55.5%) were diagnosed as being H.pylori positive.The sensitivity,specificity,and accuracy of the Stick test were 84.7%,89.9%,and 87.0%,respectively.There were 17(8.5%) falsenegative patients and 9(4.5%) false-positive patients.CONCLUSION:The Rapirun Stick test has high sensitivity,specificity,and accuracy for the diagnosis of H.pylori infection in the Vietnamese population.The test can be clinically applied in Vietnamese populations. | Duc T Quach Toru Hiyama Fumio Shimamoto Quang D Le Linh X Ho Nhu HT Vu Masaharu Yoshihara Naomi Uemura | 2014 | World Journal of Gastroenterology2014,20,17: | 4 |
